Advice please on pros and cons of a new aquisition.
1. Pam 104 Brand new or
2. Pam 312 Pre Owned from reputable dealer or
3. Pam 359 Pre Owned from reputalble dealer

As a collector which watch would I be better served with.
The 312 and 359 are the same watch with the 359 having a sandwich dial.
Is one dial more preferable for collectors than the other?
Price is not an issue as all three are around the same price.
Thanks,
Jake
